This patch factors out common implementation patterns to reduce overall kernel
code and provide a means for host bridge drivers to directly obtain struct
resources from the DT's ranges property without relying on architecture specific
DT handling. This will make it easier to write archiecture independent host bridge
drivers and mitigate against further duplication of DT parsing code.
This patch can be used in the following way:
struct of_pci_range_parser parser;
struct of_pci_range range;
if (of_pci_range_parser_init(&parser, np))
; //no ranges property
for_each_of_pci_range(&parser, &range) {
/*
directly access properties of the address range, e.g.:
range.pci_space, range.pci_addr, range.cpu_addr,
range.size, range.flags
alternatively obtain a struct resource, e.g.:
struct resource res;
of_pci_range_to_resource(&range, np, &res);
*/
}
Additionally the implementation takes care of adjacent ranges and merges them
into a single range (as was the case with powerpc and microblaze).

* Get mipi config clock source in the mipi dsi driver.
* Change clk_enable()/clk_disable() to clk_prepare_enable()/

from mipi_dsi_disp_init().
* Move mach/mipi_dsi.h to linux/mipi_dsi.h.
* Remove __devexit_p and __devexit since 3.10 kernel doesn't
support them.
* Remove struct mipi_dsi_platform_data from mach/mipi_dsi.h.
* Remove mach/hardware.h, mach/clock.h, linux/fsl_device.h
and linux/regulator/consumer.h in the drivers.
* Remove special pixel clock setting for imx6sdl since no
issue is found without it.
* Remove unused reset, lcd_power and backlight_power interfaces

* Remove unused regulator related entries in struct mipi_dsi_info.
* Remove the IOMUX_GPR3_OFFSET macro from mipi dsi driver since
the muxing is done with common regmap APIs.

During the read of NOR, the kernel actually calls the inline_map_copy_from()
to read the data out. And inline_map_copy_from() will use the memcpy_fromio()
to do the real job.
The memcpy_fromio macro maps _memcpy_fromio() in the current code.
But the _memcpy_fromio() will use readb() to do the copy work one byte
by one byte. This makes the read performance of NOR very slow(about 2~3MB/s).
A similiar discussion could be found in:
http://lists.infradead.org/pipermail/linux-arm-kernel/2009-November/003860.html
This patch replace the memcpy_fromio with memcpy which is optimized by the
kernel.

Since we need otgsc to know vbus's status at some chipidea
controllers even it is peripheral-only mode. Besides, some
SoCs (eg, AR9331 SoC) don't have otgsc register even
the DCCPARAMS_DC and DCCPARAMS_HC are both 1 at CAP_DCCPARAMS.
We inroduce flag CI_HDRC_DUAL_ROLE_NOT_OTG to indicate if the
controller is dual role, but not supports OTG. If this flag is
not set, we follow the rule that if DCCPARAMS_DC and DCCPARAMS_HC
are both 1 at CAP_DCCPARAMS, then this controller is otg capable.

Some hardware modules need strict flows according
to regulator's enable/disable, such as for i.MX6
SOC's PU regulator, there is another power gate
in GPC module, it needs to disable PU modules' clock
before PU regulator is disabled and need to enable
clock right after PU regulator is enabled, then it
can do GPC's power gate operation.
So we need to add REGULATOR_EVENT_PRE_DISABLE and
REGULATOR_EVENT_ENABLE for regulator's notifier events.

* Put the driver in drivers/media/platform/ directory instead
of drivers/media/video/ directory, since the later one is
renamed to the former one in 3.10 kernel.
* Change the ipu-v3.h header file from <mach/ipu-v3.h> to

* Change the mxc_vidioc_s_crop() function's implementation since
the definition of the vidioc_s_crop() function is modified to
make the last argument be constant.
* Set vfl_dir to be VFL_DIR_TX since the ioctrl validity checks
are improved in 3.10 kernel.
* Remove 'defaut y' setting for VIDEO_MXC_OUTPUT and
VIDEO_MXC_IPU_OUTPUT Kconfigs. They may be configured by kernel
default configure or by user.
* Make VIDEO_MXC_OUTPUT Kconfig depend on FB_MXC Kconfig since
we need framebuffers to be rendered.
* Make VIDEO_MXC_IPU_OUTPUT Kconfig be tristate.

cpufreq: interactive: New 'interactive' governor
This governor is designed for latency-sensitive workloads, such as
interactive user interfaces. The interactive governor aims to be
significantly more responsive to ramp CPU quickly up when CPU-intensive
activity begins.
Existing governors sample CPU load at a particular rate, typically
every X ms. This can lead to under-powering UI threads for the period of
time during which the user begins interacting with a previously-idle system
until the next sample period happens.
The 'interactive' governor uses a different approach. Instead of sampling
the CPU at a specified rate, the governor will check whether to scale the
CPU frequency up soon after coming out of idle. When the CPU comes out of
idle, a timer is configured to fire within 1-2 ticks. If the CPU is very
busy from exiting idle to when the timer fires then we assume the CPU is
underpowered and ramp to MAX speed.
If the CPU was not sufficiently busy to immediately ramp to MAX speed, then
the governor evaluates the CPU load since the last speed adjustment,
choosing the highest value between that longer-term load or the short-term
load since idle exit to determine the CPU speed to ramp to.
A realtime thread is used for scaling up, giving the remaining tasks the
CPU performance benefit, unlike existing governors which are more likely to
schedule rampup work to occur after your performance starved tasks have
completed.
The tuneables for this governor are:
/sys/devices/system/cpu/cpufreq/interactive/min_sample_time:
The minimum amount of time to spend at the current frequency before
ramping down. This is to ensure that the governor has seen enough
historic CPU load data to determine the appropriate workload.
/sys/devices/system/cpu/cpufreq/interactive/go_maxspeed_load
The CPU load at which to ramp to max speed.
